Case Study: Stratum Filters Save Sausage Maker 50% on Filter Costs



Application: Slurry for making sausage casings

Previous Product Used: 3M Cuno Polynet 1 micron

Graver Product: Graver Stratum A 1 micron and Stratum C 3 micron

Discussion:

A manufacturer of sausages was looking for a better filtration solution for their cellulose slurry. They were using Cuno Polynet 1 micron absolute rated filters to maintain a specific turbidity level of this mixture of cellulose fibers, sulfuric acid and sodium salts. Initially the customer tried STA 1 micron, which achieved the desired turbidity, but life was shorter than the 3M filter. It was decided to try Graver Stratum C 3 micron to see if the turbidity target could be met, while offering cost savings.


Results:

  • The STC 3 micron met the turbidity specification.

  • STC 3 micron filters had longer life than STA 1um and matched the Polynet life.

  • The dirt capture within the STC 3 filters was highly uniform, but with white area near core indicating no pass through of captured contaminant.

  • The Polynet filters showed penetration of contaminant all the way through to the core and also held up excess fluid between layers.

  • Cost savings were immense for the customer. They went from paying $22 for the Cuno Polynet to paying $10.50, a savings of over 50%.

  • The engineer gathered sufficient data to win corporate approval to change the filter specification and STC 3 filters were adopted in this company’s plants around the world. The engineer was rewarded for his efforts with a promotion!
